Objective:
To explore clinical efficacy of Locking loop stitch with suture-bridge technique in repair of acute closed distal Achilles tendon rupture by using suture anchors.
Methods:
From July 2019 to March 2021, 20 patients with acute closed distal Achilles tendon rupture were treated by minimally invasive suture anchor locking suture bridging repair technique. Among them, including 18 males and 2 females, aged from 19 to 52 years old with an average of(40.0±9.0) years old. Complications were observed, and recovery of ankle function was evaluated by American Orthopaedic Foot & Ankle Society(AOFAS) ankle and hindfoot function scoring system before operation and 1 year after operation.
Results:
All patients followed up from 6 to 18 months with an average of (12.0±3.2) months. The incisions were healed at stageⅠwithout infection and skin necrosis occurred;no gastrocnemius nerve injury and deep vein thrombosis of the lower extremities occurred;and no heel pain and Achilles tendon re-rupture occurred. AOFAS scores of ankle and hindfoot increased from(59.0±4.3) before opertaion to(95.1±2.6) at 1 year after operation (t=-32.1, P<0.05).
Conclusion:
The effect of locking suture bridging with suture anchor nails to repair acute distal Achilles tendon rupture is definite, and it could reduce incidence of complications such as Achilles tendon re-rupture, nerve injury, and skin necrosis, which has advantages of small surgical trauma, reliable anastomosis method and good functional recovery, and is an ideal method for treating acute closed distal Achilles tendon rupture.
